PCA9510 Overview
The PCA9510 and PCA9511 are hot swappable I2C and SMBus buffers that allows I/O card insertion into a live backplane without corrupting the data and clock buses. Control circuitry prevents the backplane from being connected to the card until a stop mand or bus idle occurs on the backplane without bus contention on the card. When the connection is made, the PCA9510 and PCA9511 provides bi-directional buffering,...
PCA9510 Key Features
- Bi-directional buffer for SDA and SCL lines increases fanout and
- patible with I2C standard mode, I2C fast mode, and SMBus
- Rise time accelerator threshold of 0.6 V
- Active high ENABLE input
- Active high READY open-drain output
- High impedance SDA and SCL pins for VCC = 0 V
- 1 V precharge on all SDA and SCL lines (PCA9510 IN only)
- Supports clock stretching and multiple master
- cPCI, VME, AdvancedTCA cards and other multi-point backplane
